FDNY firefighters are fighting the department’s snooping into their personal phone records to hunt the source of news leaks.

Outraged by FDNY tactics — including subpoenaing cellphone records — the Uniformed Fire Officers Association “strongly recommends” that members not give the department their numbers and delete them from their personnel files, The Post has learned.

The department needs cellphone numbers to reach off-duty personnel in a major emergency. But recently it has been searching phone records to check if members called reporters.

“The FDNY is so paranoid about leaks to the media, they’re scanning phone records and have a dedicated operation to flush them out,” a retired member said. “They’re more concerned about bad press than their bad policy.”

FDNY spokesman Jim Long declined to comment on “open and active investigations.”
